Questions, Answered
The mattress questions we actually get asked.
If your question isn't here, call our Brantford showroom at 519-770-0001 or stop in at 441 1/2 West Street. A real person answers the phone.
What size mattress should I get?
Twin (38 x 75 in) for kids and single sleepers. Twin XL (38 x 80 in) for tall single sleepers and teens. Double (54 x 75 in) for couples in compact rooms. Queen (60 x 80 in) is most popular. King (76 x 80 in) for couples with kids or pets. California king (72 x 84 in) for taller couples.
How much room do I need around the bed?
Leave 24-30 inches of walkway on at least one long side. Two sides clear is ideal. Add 12-18 inches for a nightstand. A queen needs a room at least 10 x 12 ft to feel comfortable; a king wants 12 x 14 ft.
Queen vs king: which for couples?
Queen if room is under 12 x 12 ft or you sleep close. King if you have the room and one of you moves a lot, snores, or shares with pets/kids. King effectively gives each partner a twin XL of space.
What's a California king vs a regular king?
California king is 72 x 84 inches — narrower but longer than a regular king (76 x 80 in). Cal king suits sleepers over 6'4" who want length. Regular king suits sleepers under 6'4" who want width.
Do you sell RV and truck mattresses?
Yes. CJ Mulholland custom RV and truck mattresses, made in Canada, available at our Brantford showroom. Available in custom sizes for sleeper trucks, RVs, and trailers. Call 519-770-0001 with your dimensions.
