Frequently asked questions
The Cozey Foam Mattress is a 25 cm (10 in) medium-firm, all-foam mattress with no coils. Under the quilted cover are 5 cm (2 in) of Serene® comfort foam, 5 cm (2 in) of high-density transition foam and 15 cm (6 in) of high-density support foam. The comfort layer contours to your body and the support foam keeps your spine aligned. Standard fitted sheets fit.
The Cozey Foam Mattress is medium-firm, around 5.5 to 6 out of 10. The dense foam core absorbs your weight evenly, so you settle slightly into the bed rather than lying on top of it. It suits side and back sleepers who like a cradled feel. It comes in one feel, so it is not the right pick if you need a soft or very firm bed.
Yes. The Cozey Foam Mattress absorbs motion where it starts: its 15 cm (6 in) high-density foam core takes in movement with very little bounce and no noise. That means a partner getting up early is less likely to wake you. It suits couples where one partner is a light sleeper or the other tosses and turns through the night.
Yes, for many warm sleepers. The Cozey Foam Mattress uses Serene® comfort foam, which is not temperature-sensitive and, in Carpenter Co. lab tests on foam samples, released heat 18% faster than memory foam in the first 30 minutes. Serene® has no gel or active cooling, so it avoids trapping heat like memory foam rather than cooling you.
Yes. The Cozey Foam Mattress was designed for side and back sleepers. Its 5 cm (2 in) Serene® comfort layer lets shoulders and hips sink in: in Carpenter Co. pressure mapping on 5 cm (2 in) foam samples, Serene® had about 20% lower average shoulder pressure than memory foam (19.2 vs. 24.0 mmHg) with a person on their side. It suits side sleepers who like a close, cradled feel.
No. The Cozey Foam Mattress uses Serene® foam, a polyurethane foam developed by Carpenter Co. that feels close to memory foam but is a different material, built with microscopic air capsules. In Carpenter's lab tests on 5 cm (2 in) foam samples, Serene® rebounded about four times faster than memory foam (about 20% vs. 5%), so rolling over takes less effort, and it showed no detectable temperature sensitivity, so it does not firm up in a cold bedroom.
In Cozey's durability testing, which simulates 15 years of nightly use, the Cozey Foam Mattress lost less than 6% of its firmness. That means it should feel close to how it did in year one for a long time. It is backed by a 15-year limited warranty that covers visible, permanent indentations of 2.5 cm (1 in) or more on proper support; normal softening and changes in comfort preference are not covered.
The Cozey Foam Mattress is rated for up to 113 kg (250 lb) per sleeper. Above roughly 104 to 113 kg (230 to 250 lb), most people get better long-term support from a thicker or firmer mattress built for that load. For sleepers within that range, its 15 cm (6 in) high-density support foam keeps hips from sinking too far for side and back sleeping.
The Cozey Foam Mattress ships rolled in one box with a handle, 112 x 44.5 x 44.5 cm (44 x 17.5 x 17.5 in) for every size. The box weighs 24 kg (52 lb) for a Full, 28 kg (62 lb) for a Queen and 33 kg (72 lb) for a King. Unroll it on your bed base, cut away the plastic, and it is ready to sleep on in about 30 minutes; full shape takes 24 to 48 hours.
On the Ara Bed, the Cozey Foam Mattress sits directly on Ara's black powder-coated steel frame and 15 mm laminated veneer lumber (LVL) slats, spaced about 5.7 cm (2.2 in) apart on Queen and King, with no box spring needed. For another platform bed, follow that frame's instructions. Cozey does not state adjustable-base compatibility, so ask the Customer Happiness team before pairing it with an adjustable base or a specific foundation.
Yes. Every foam in the Cozey Foam Mattress is CertiPUR-US® certified, which means it is tested for formaldehyde, heavy metals, phthalates and VOC emissions. The mattress is designed by Cozey's team in Montreal. It suits shoppers who want an all-foam, medium-firm mattress with certified foams in every layer, from the 5 cm (2 in) Serene® comfort layer to the 15 cm (6 in) support foam.
Yes. Cozey's U.S. pop-up stores display the upholstered Ara Bed, and the team there can help you order the Cozey Foam Mattress with it. That lets you see the bed it pairs with, take home fabric swatches and get free design help before you buy. Once it arrives, the 100-night trial lets you test the mattress at home.
Yes. The Cozey Foam Mattress comes with a 100-night trial with no minimum number of nights. If it is not the right fit, Cozey schedules a free pickup and gives a full refund, and you do not need the original box. Returned mattresses are donated whenever possible, so a mattress that does not suit you is not sent to landfill.
The Cozey Foam Mattress suits side and back sleepers, and couples, who want a close, cradled feel with little motion transfer. Its 5 cm (2 in) Serene® comfort layer relieves pressure at shoulders and hips, and its 15 cm (6 in) high-density support foam keeps the spine aligned at a medium-firm 5.5 to 6 out of 10. It is not the right pick if you weigh more than 113 kg (250 lb) or need a soft or very firm bed.
