The 30-second verdict
Yes for most buyers who want a medium-feel hybrid. The catch is that heavier sleepers may find it too soft. It is rated 4.5 out of 5 stars from 512 reviews. If you sleep warm, on your back, or on your stomach and weigh under 230 lb, the Allswell 10-inch Hybrid Mattress may fit better; Sleep Foundation rated it 8.0/10. Buy it only if a medium hybrid feel fits your sleep preferences.

Owner rating4.5 / 5512 reviews on costco.com
Sizes2Queen to King
Pros
Layered foam and coils. Novaform lists 3 inches of EVENcor GelMax memory foam, 3 inches of air-channel foam, and 6 inches of individually wrapped coils.
Cooling materials. Novaform lists phase change gel for temperature regulation and cool-to-touch fibers in the quilted cover.
Easy care. Novaform says you do not need to flip it and recommends occasional flat rotation.
Fiberglass statement. Novaform says its mattresses and toppers contain absolutely zero fiberglass.
Cons
Adjustment period. Novaform says it may take up to 1-2 weeks to get used to the feel.
Cover warranty limit. The model warranty excludes imperfections of the fabric cover.
Queen moving weight. A Queen weighs 90.8 lbs, so plan for help when moving it.
How firm is the ComfortGrande 14″ Advanced Hybrid Gel Memory Foam Mattress, and which firmness should you pick?
The listed firmness choice is Medium, so choose it if you want a mattress labeled Medium. Use your past mattress preferences to guide the decision, rather than assuming the label guarantees a particular feel for you. Before ordering, check the seller’s return terms and whether you can try the mattress in person. That gives you a next step if the feel does not suit you. Do not use the label alone to decide whether the bed fits your sleeping position.

Is the ComfortGrande 14″ Advanced Hybrid Gel Memory Foam Mattress good for back pain?
Novaform says its six-inch individually wrapped coils offer precision back and body support. That is the brand's description of the coil system. If back pain is part of your decision, weigh this as Novaform's support claim and consider whether the mattress feels comfortable for you. Your own comfort should guide the choice, rather than relying on a single support description.
What the brand says
Novaform says its six-inch individually wrapped coils offer precision back and body support.
Ongoing back pain? Ask a doctor or physical therapist what support your back needs before you buy.
Novaform lists a plush quilted cover with cool-to-touch fibers and EVENcor GelMAX™ memory foam infused with phase change gel for temperature regulation. That puts a listed cooling feature in the cover and another in the foam. Compare these material details with descriptions for other mattresses on your shortlist, then choose the design that best fits your preferences before you buy.

Choose between Queen and King by matching the dimensions to your frame and room first. Use the table to compare their footprints, then check your frame and bedroom space before ordering. That can help you avoid choosing a size that will not fit in your room.

The cover has a mixed-fiber top and a polyester border. The top is 46% polyester, 37% nylon, 16% polyethylene, and 1% spandex. The border is 100% polyester.
CertiPUR-US® certification covers the foam, not the whole bed. Novaform says the certified foam has no heavy metals or phthalates, low VOCs, and no ozone depleters. This gives you a defined scope for the foam’s chemical and emissions claims.
Does the ComfortGrande 14″ Advanced Hybrid Gel Memory Foam Mattress have fiberglass?
Novaform says this mattress contains absolutely zero fiberglass. The statement covers its mattresses and toppers, so it applies to this bed. If avoiding fiberglass is your priority, this is a clear assurance from the maker to weigh when deciding whether the mattress fits that preference. Use Novaform's statement as you make your choice.
What the brand says
Novaform says its mattresses and toppers contain absolutely zero fiberglass.
Platform beds, standard box springs, and adjustable bases are compatible with this mattress. For slats, use a well-ventilated base with slats spaced less than six inches apart. Choose a base that provides proper airflow and support: the brand says a base without them will void the limited warranty. Check those conditions before choosing a base.

How long will it last, and does it need flipping or rotating?
Does it need flipping or rotating?
Novaform says the ComfortGrande does not need flipping; it recommends an occasional flat rotation for best performance.
Novaform says it may take up to 1-2 weeks to get used to the new feel. This adjustment may matter more if you are used to a standard spring mattress. Give yourself that full adjustment time before judging comfort, rather than deciding from the first night.
Rotate or flip
No flipping needed; rotate occasionally using a flat rotation. No interval is stated.
Break-in
Up to 1-2 weeks to get accustomed to the new feeling.
The brand lists delivery in 5 - 7 business days. If you need your current mattress until this one arrives, place your order with that window in mind so a bed remains available while you plan the changeover to your new mattress.
Novaform lists this model with a 20-year limited warranty, but its terms exclude fabric-cover imperfections, including pilling, excess threads, and wrinkling. If you notice one of these issues, the warranty will not cover it, so factor that limit into your decision.
This model
The model warranty excludes fabric-cover imperfections; Novaform's general FAQ says its product warranties cover defects in the fabric cover and foam.
Owner feedback includes praise for soft comfort and value, alongside warnings that the bed may feel too soft. The retailer's customer reviews give it 4.5 out of 5 stars from 512 reviews, a strong score across many ratings. One owner praised its soft, comfortable feel; another, after three months, said it was good value for lighter sleepers.
Softness may be a fit concern for heavier sleepers: one hybrid owner said it might feel too soft. An owner-review summary also lists softness and back or hip pain among the complaints. Treat those as possible downsides, not a prediction of how you will sleep.
