# Havnby Perfect Fit Bed Sheet for CloudCore Tesla Mattress Review

Havnby Perfect Fit Bed Sheet: a $99 fitted cover for the CloudCore Model S/3/X/Y mattress. Evidence is limited to official Havnby catalog data and a named competitor's listing, checked 24 August 2026; no score or hands-on result is assigned.

Primary sources checked

## What the evidence can prove: Secondary research — no score assigned

Seller listing for live verification: August 24, 2026

The catalog record clearly exposes the sheet's price, SKU, weight, tag list and publication date, and the SKU prefix ties it directly to the CloudCore Model S/3/X/Y mattress. It also directly exposes a copy-paste error: the feature bullets describe mattress pump hardware that a sheet does not have. Havnby does not publish fabric type, dimensions, an attachment method or a review count for this item, and the sheet's own tags omit Model S despite the title and body text naming it. The $24 rival's competing listing publishes a material spec, a stated attachment method and 41 reviews, more documented evidence than Havnby's $99 listing offers for this item.

Quick take **Secondary research — no score assigned**

Havnby sells the Perfect Fit Bed Sheet for CloudCore Tesla Mattress at $99, checked on 24 August 2026. Havnby's listing names Model S, 3, X and Y, though the sheet's own catalog tags omit Model S and no dimensions are published for the sheet or its companion CloudCore mattress. Buyers on a budget should know a rival Tesla-mattress vendor sells a fitted sheet for Model 3 and Model Y at $24, with a published 100 GSM microfiber spec that Havnby's listing does not match anywhere.

Practical ownership review

## Six checks before you buy

A $99 fitted cover for the CloudCore Hybrid Support Mattress for Tesla Model S/3/X/Y. The sheet's SKU shares a prefix with that mattress, and the listing names four Tesla families, but no fabric, dimension or attachment figure is published. The record separates those published facts from fit, comfort and durability outcomes that have not been independently established.

1. 01 **Packing and cargo space** Havnby publishes only a shipping weight for this item, 608 g (1.3 lb). No folded, rolled or packaged size is stated, and no storage bag is mentioned. A sheet does not need a pump or stuff sack the way a mattress does, but Havnby's listing does not say whether it ships folded flat, rolled, or bagged.
2. 02 **Fabric, foam and build quality** Havnby states no fabric type, weave, thread count or GSM figure anywhere in the product text for this sheet. Havnby's product images include a graphic captioned "Breathable Fabric," showing steam rising from a water jar under stretched fabric, but no air-permeability figure or test method backs that claim in the item's text description. A rival Tesla-mattress vendor states its $24 sheet is 100 percent polyester brushed microfiber at 100 GSM, a figure Havnby does not match with any number.
3. 03 **Pump, power and setup** The sheet's own feature bullets describe a built-in pump that inflates in about 70 seconds and deflates in about 85 seconds. Those lines are copied from Havnby's foam mattress listings, including the CloudCore Model S/3/X/Y mattress this sheet is designed to cover, and do not describe a flat sheet. Havnby does not separately describe how the sheet attaches to the mattress, whether by elastic corners, straps or a fitted pocket. The $24 rival's competing listing states its attachment method directly: elastic wraps around the rear wheel wells for Model Y, and elastic wraps between the rear headrests and the sub-trunk cover for Model 3.
4. 04 **Sleep quality and support** Havnby's only comfort-adjacent claim is the marketing line "keeping your sleep setup cleaner, quieter, and easier to maintain." No texture, softness or temperature claim is stated in the product text, and no test or owner feedback is published for this SKU. Official photos show a gray fabric color, though no color is named in the text description.
5. 05 **Cleaning, moisture and storage** Havnby states no washing method, fabric-care symbol or removable-cover instruction for this sheet. The $24 rival states its competing sheet is machine washable directly in its product text. This record does not state Havnby's warranty or return terms for this specific item, because the sheet's own catalog entry does not include them; readers should check Havnby's current site-wide return policy before ordering.
6. 06 **What remains unresolved** The $99 price is about four times a rival's $24 sheet, and Havnby publishes no fabric, GSM or dimension figure to support the gap; The five feature bullets describe a pump, inflation and deflation, copied from a mattress listing and not accurate for a sheet; The sheet's own catalog tags omit Model S, though the title, body text and companion mattress all include it; No dimensions are published for the sheet or for the CloudCore mattress it is designed to cover; No attachment method is described, despite the Perfect Fit Bed Sheet product name

## Decision summary

Havnby sells the Perfect Fit Bed Sheet for CloudCore Tesla Mattress as a separate $99 accessory. This is a secondary-research review based on Havnby's own product catalog record and a named competitor's product page, checked on **24 August 2026**. No hands-on fit test, wash test or comfort test was performed for this review. Every figure below traces to Havnby's product feed or to a competitor's own page, not to an independent measurement.

At the source check, the sheet showed one price, $99.00, with no separate markdown from Havnby: the compare-at price also reads $99.00. The nearest published alternative, a rival Tesla-mattress vendor's fitted sheet for Tesla Model 3 and Model Y, sells for $24.00. That four-times price gap is the main question this review answers.

Havnby's storefront-wide code AWD applies a 10 percent discount, cutting the $99 sheet to $89.10, a $9.90 saving. The discount narrows the gap with the $24 rival. It does not close it.

## Which CloudCore mattress and Tesla models this sheet fits

Havnby's title and body copy point to one specific companion product: the CloudCore Hybrid Support Mattress for Tesla Model S/3/X/Y, priced at $399. The sheet's SKU, YUN-BEDSPREAD, shares the YUN prefix with that mattress's own SKU, H-yun-mattress. No other CloudCore mattress in Havnby's catalog, including the CloudCore SUV mattress, carries a matching SKU prefix. That match is the clearest evidence that this sheet is built for the Model S/3/X/Y mattress and not for Havnby's other CloudCore lines.

The mattress itself lists a selector with four Tesla families: Model Y for 2020 through 2026, Model 3 for 2017 through 2026, Model X for 2015 through 2026, and Model S only for 2023 through 2026. Havnby does not publish a length, width or height figure for this mattress. Without a mattress dimension on record, a buyer cannot check the sheet against the mattress it covers, only against the model names both products share.

A gap remains inside Havnby's own data. The sheet's catalog tags list codes for Model 3, Model X and Model Y, but no Model S code appears anywhere, even though the sheet's title and body text name Model S directly and the companion mattress sells Model S variants for 2023 through 2026. Buyers with a Model S should confirm fit with Havnby directly before ordering.

## $99 versus a $24 rival sheet: what the price gap buys

A rival Tesla-mattress vendor sells a fitted sheet for the Tesla Model 3 and Model Y at $24.00. The $24 rival states the material directly: 100 percent polyester brushed microfiber at 100 GSM (grams per square meter, a standard fabric-weight measure). It also states the sheet is breathable, wrinkle, fade and stain resistant, allergen-free and machine washable, in white. The $24 rival describes how the sheet attaches: elastic wraps around the rear wheel wells for Model Y, and elastic wraps between the rear headrests and the sub-trunk cover for Model 3. The product carries 41 reviews, with 83 percent five-star, 15 percent four-star and 2 percent three-star ratings. The $24 rival ships free within the USA, ships worldwide, and offers 30-day returns. It does not state exact dimensions and offers no discount code.

Havnby's $99 listing does not match any of those figures: no fabric type, no GSM, no thread count, no color, no attachment mechanism and no review count. The one advantage Havnby claims over the $24 rival is wider Tesla coverage, Model S and Model X in addition to Model 3 and Model Y, but that claim comes from marketing copy alone. The sheet's own tags do not confirm Model S, and no dimension figure from either seller lets a buyer confirm fit across four very different Tesla cabin shapes.

The $75 price gap is not supported by the published evidence. The $24 rival publishes a material spec, a review record and a stated attachment method for $24. Havnby publishes none of those three things for $99.

## What the official listing does not say

The sheet's five feature bullets read: multi-use fit, foam-backed comfort, fast setup with a built-in pump that inflates in about 70 seconds, easy pack-down that deflates in about 85 seconds, and compact storage. Those bullets describe an air-and-foam camping mattress, not a flat sheet. A bed sheet has no pump and cannot inflate or deflate. The text is copied from Havnby's own mattress listings, including the CloudCore Model S/3/X/Y mattress this sheet is meant to cover, and was not rewritten for a sheet product.

Havnby's product images include a graphic captioned "Breathable Fabric," showing steam rising from a water jar under a stretched piece of fabric. No air-permeability figure, test method or GSM number appears in the item's text description to support that claim. Official photos, separate from that graphic, show the sheet folded with gathered, elasticized corners, consistent with a fitted-sheet cut, and a gray fabric color, though no color is named in the product text.

### Documented strengths

- SKU YUN-BEDSPREAD matches the YUN prefix on the companion CloudCore Model S/3/X/Y mattress SKU, H-yun-mattress
- Title and body copy claim fit across four Tesla families, wider than a rival's stated Model 3 and Model Y coverage
- Official photos show gathered, elasticized corners consistent with a true fitted-sheet cut
- Havnby publishes an exact 608 g shipping weight for the sheet

### Concrete tradeoffs

- The $99 price is about four times a rival's $24 sheet, and Havnby publishes no fabric, GSM or dimension figure to support the gap
- The five feature bullets describe a pump, inflation and deflation, copied from a mattress listing and not accurate for a sheet
- The sheet's own catalog tags omit Model S, though the title, body text and companion mattress all include it
- No dimensions are published for the sheet or for the CloudCore mattress it is designed to cover
- No attachment method (elastic, straps or a fitted pocket) is described, despite the "Perfect Fit Bed Sheet" product name

## Care and ownership terms

Havnby's listing for this sheet states no washing method, no fabric-care symbol and no removable-cover instruction. The marketing line "keeping your sleep setup cleaner, quieter, and easier to maintain" is a general claim, not a care instruction. The $24 rival, by contrast, states its sheet is machine washable in the product text.

This record does not state Havnby's warranty or return terms for this item; the catalog entry does not include them. Readers should check Havnby's current site-wide return policy before ordering.

## Who should consider it?

Consider it when a buyer already owns the CloudCore Hybrid Support Mattress for Tesla Model 3, Model X or Model Y and wants a cover from the same seller, and when matching seller and mattress brand matters more than a published material spec.

## Who should not buy it?

Skip it when a stated fabric type, GSM figure or wash instruction must be known before ordering, when a Model S owner needs the fit confirmed in writing, or when budget matters most: the $24 rival publishes more product detail at a quarter of the price.

## FAQ

### Does this sheet fit every Tesla model?

Havnby's title and body text name Model S, 3, X and Y. The sheet's own catalog tags list only Model 3, Model X and Model Y codes, with no Model S code present.

### What fabric is the sheet made from?

Havnby does not state a fabric type, weave or GSM figure anywhere in the product listing. The $24 rival's sheet states 100 percent polyester brushed microfiber at 100 GSM.

### Why does the description mention a pump and inflation time?

Those lines are copied from Havnby's own foam mattress listings. A bed sheet does not inflate or deflate, and the description was not rewritten for this product.

### Is there a cheaper alternative?

A rival Tesla-mattress vendor sells a fitted sheet for Tesla Model 3 and Model Y at $24.00, with a stated material spec and 41 published reviews. It does not cover Model S or Model X.

## Bottom line

Havnby's Perfect Fit Bed Sheet shares a SKU family with the CloudCore Model S/3/X/Y mattress and claims wider Tesla coverage than its main competitor. Havnby does not publish a fabric type, a dimension figure or an attachment method to support its $99 price, and its own feature bullets describe mattress hardware that a sheet does not have. Buyers who need documented material and fit data at a lower price should compare the $24 rival's sheet before ordering.
